The World Association of Theoretical and Computational Chemists (WATOC) is a scholarly association founded in 1982 "in order to encourage the development and application of theoretical methods" in chemistry, particularly quantum chemistry and computational chemistry.[1] It was originally called the World Association of Theoretical Organic Chemists,[1] but was later renamed the World Association of Theoretically Oriented Chemists,[3] and in 2005 renamed once more to the World Association of Theoretical and Computational Chemists.[1]
